Subtraction works

I finally was able to subtract a Post Angio image from a Pre Angio image. The images are MRIs showing the pulmonary vessels. Subtraction, although a very trivial procedure, took me some time to figure out since I was new to the IDE.

The subtracted iamge reveals the blood vessels. Daniel has suggested that I perform a MIP (Maximum Intensity Projection) rendering on the vessels to analyze the structure. MIP can be easily implemented using the VTK library. I am doing some background reading on basic Computer graphics concepts such as volume/surface rendering. I have got hold of some papers and a book on the VTK library.
